1 NVIDIA Tegra NAND Flash controller
4 - compatible: Must be one of:
5   - "nvidia,tegra20-nand"
6 - reg: MMIO address range
7 - interrupts: interrupt output of the NFC controller
8 - clocks: Must contain an entry for each entry in clock-names.
9   See ../clocks/clock-bindings.txt for details.
10 - clock-names: Must include the following entries:
11   - nand
12 - resets: Must contain an entry for each entry in reset-names.
14 - reset-names: Must include the following entries:
15   - nand
18 Individual NAND chips are children of the NAND controller node. Currently
19 only one NAND chip supported.
22 - reg: An integer ranging from 1 to 6 representing the CS line to use.
25 - nand-ecc-mode: String, operation mode of the NAND ecc mode. Currently only
27 - nand-ecc-algo: string, algorithm of NAND ECC.
28 		 Supported values with "hw" ECC mode are: "rs", "bch".
29 - nand-bus-width : See nand-controller.yaml
30 - nand-on-flash-bbt: See nand-controller.yaml
31 - nand-ecc-strength: integer representing the number of bits to correct
32 		     per ECC step (always 512). Supported strength using HW ECC
34 		     - RS: 4, 6, 8
35 		     - BCH: 4, 8, 14, 16
36 - nand-ecc-maximize: See nand-controller.yaml
37 - nand-is-boot-medium: Makes sure only ECC strengths supported by the boot ROM
39 - wp-gpios: GPIO specifier for the write protect pin.
